Additional file 4 of Behavioural susceptibility to environmental influences in obesity– evidence from a companion animal model

Additional file 4. Effect of owner management and other risk factors on BCS were different between contrasting obesity risk groups. Effect size β and significance level of biological and environmental factors on BCS between dogs in different Food Motivation Score tertile are shown. Values were extracted from a simple linear regression model that included sex, neuter status and age with two-way interactions and Owner Intervention Score, Restriction of Human Food Score and Exercise Score in two-way interaction terms with Food Motivation Score tertile. To obtain comparable effect β values the model was run three times, each with a different Food Motivation Score tertile group as a reference range, allowing us to obtain β values for the corresponding tertile. In each cell, β value is expressed with level of significance in parentheses. Age effects are expressed per year; Sex (0 = Female and 1 = Male); neutering status (0 = entire, 1 = neutered).
